WIP: Basic Filestore implementation.

[kevina]

@whyrusleeping this is not 100% what you want but it is close. It still uses bits of the multi-blockstore but doesn't use any of the parts you don't like.

Things that still need to be done (for this part):

• Implement DeleteBlock for the filestore
• Config option to enable filestore (it is now always enabled due to the complete remove of ipfs filestore commands, including ipfs filestore enable)
• Implement a correct Has method that checks to make sure the content is still available

Things you may still not like:

• "ipfs add" will not add blocks if any of them happen to be in the filestore

Things I don't like:

• way to many, most of which needs to be in separate issues.

Others: see #2634 for the full implementation.

@jbenet You mentioned the other day that you wanted to review this. If you find time soon to do so that would be great.

@jbenet I am not sure what @whyrusleeping told you but please note that this is only a small fraction of the full filestore code with very little of the functionality of #2634. I do not consider this very useful, as it doesn't even provide a way to list what is in the filestore. We also had some rather strong disagreements that I have not been able to write (publicly) about yet.

The test cases are also not as comprehensives as I would like as most of the test cases rely on functionality not in this pull request.

#3629 was merged in favor of this one.Closing now

@Kubuxu can we move the branch kevina/filestore-basic to go-ipfs-archived?

It will be moved in a month.
